Personally I felt like it had a more smooth transition to a snowier solution, for this previous weekend system, than some of the more traditional models such as UK and GFS which I believe jumped around a bit more. I am surprised at all the NAM hate I keep reading about (mostly in the MA forum). No doubt it is a shorter range model but I lurked some over the last few years and although they all miss some times, the NAM seems quite good at catching late trends in storms within 48 hours.
